PROCESS TO EVALUATE CORNERING FOR AN AUTOMATIC GEARBOX

摘要

A process for evaluation of cornering of a vehicle equipped with an automatic transmission by use of electronic transmission control device having a calculation unit, a micro-controller, a memory device and a control device for start up of a hydraulic transmission control device. During a first processing operation (S1), a transverse acceleration (a_Quer) of the vehicle is determined by the calculation unit (30) from wheel speed (n_Rad) of the vehicle measured by a measuring device (34). During a second processing operation (S2), a driver-type theoretical value (FT_Soll) is determined from a vehicle transverse acceleration (a_Quer) and a vehicle speed (v_F). A gear change characteristic line (SL) is determined, based upon an increment (INKR) between the driver-type theoretical value (FT_Soll) and a driver-type actual value (FT_Ist), from several gear change characteristic lines each one associated with a certain driver type or cornering style.
